The small orange orangutan sat in the test chamber staring through the glass window at the junior research assistant, wide-eyed and curious.
It was scheduled for an experiment with SCP-963, and the research assistant was supposed to watch the chimp until the test, but lunch was nearing and his stomach rumbling.
He wanted to get some pizza before the lunch room ran out, so with the curious orangutan staring, he took his keycard and got a head start to the lunch rush.
The orange fuzbal stood still before taking out from under there bum a keycard he had nicked from a researcher earlier in the day, and as the saying gose monkey see monkey do.
As the monkey left the small room, he began making his way through the gray office hallways twisting and turning, till all of a sudden a metal door opened in front of them as a security guard wearing black and white armor walked out.
The man called out to his fellow guards saying
“ I'm heading to the lunchroom early, so don't let 106 out while I'm gone.”
he said in a joking voce. As he walked out, the small orangutan slipped in before the door automatically closed.
The monkey stared complexed as he saw the large magnetically suspended containment chamber having not a clue what it was.
The monkey grew uncomfortable as he felt a sudden wave of dread from whatever was in that chamber.
He somehow slipped past the 2 guards chatting to each other, waiting for the afternoon shift to take over so they can go to lunch and get that amazing pizza, but they did notice when an orange orangutan locked himself in the magnetic suspension control room.
The 2 guards frantically bashed against the reinforced metal door yelling, screaming at the monkey
“TO GET AWAY FROM THE SWITCH!”.
Despite their efforts, the monkey grabbed the switch and turned it off, slowly lowering the containment cell.
Both guards pointed their rifles at the cell waiting for something to happen.
“…Maybe it doesn't want to esca-…”
Just then a bony, black, sludge-covered arm phased through the floor, through the guards armor, and even his skin, grabbing the very bone of his leg.
The guard let out a blood-curdling scream as the black sludge began eating away at his flesh from the inside-out, just before he was yanked through the ground into 106’s little playground.
Incident report 106-██ :
SCP-106 had escaped containment for about 45 minutes.
In this time, it had killed about 22 researchers and 17 guards most of which were attending lunch.
1 MTF guard officer was found 4 days after containment breach.
40% of their skin was missing and had nearly suffocated on nearly 60 teeth lodge in their throat identified to belong to his MTF team stationed at SCP-106 containment cell.
